In RFID systems, the reader usually identifies all the RFID tags in the interrogation region with the maximum power. However, some applications may only need to identify the tags in a specified area, which is usually smaller than the reader’s default interrogation region. In this paper, we respectively present two solutions to identify the tags in the specified area. The principle of the soluti...

Radio frequency identification (RFID) technology is becoming increasingly attractive because of its high storage capacity and reprogrammability. There is a challenge to be overcome when a reader needs to read a number of tags within the reader’s interrogation zone at the same time. In this paper, we present an anti-collision scheme in a RFID system. The scheme is based on the dynamic framed ALO...

This paper addresses the Hardware Trojan issues in passive EPC C1G2 RFID Tags. We propose in this paper to study the insertion of malicious circuit in EPC GEN2 RFID tags. The description and the implementation of several different Hardware Trojans are first discussed. Then they are all evaluated in an EPC GEN2 environment using a dedicated FPGA based tag emulator. The evaluation focuses on crit...

The book provides a comprehensive coverage on most recent developments in chipless and conventional RFID. It covers a wide range of topics from component level design, analysis, and development, to system integration, middleware, anti-collision, and security protocols. The chipless RFID will bring revolutionary impacts on low-cost item tagging in this millennium. The RFID based sensors and RF s...

We investigate the applicability of passive RFID systems to the task of identifying multiple tagged objects simultaneously, assuming that the number of tags is not known in advance. We present a combinatorial model of the communication mechanism between the reader device and the tags, and use this model to derive the optimal parameter setting for the reading process, based on estimates for the ...

-------------------------------------------------------------------ABSTRACT-------------------------------------------------------------Now a day’s mobile technology plays key role, in various environments identification of objects can be done manually, to improve the efficiency of an identification of objects we are using RFID tags. RFID tags track objects in supply chains, and are working the...

RFID (Radio-Frequency IDentification) is a key emerging technology for supply-chain monitoring and detection of counterfeit and grey-market goods. The most prevalent RFID tags are, however, simply “wireless barcodes,” themselves vulnerable to cloning and counterfeiting. While continuous monitoring can, in principle, detect cloning attacks, real-world supply chains often contain significant blin...

This thesis addresses the problem of providing secure protocols for the practical application of low cost Radio-Frequency Identification (RFID) tags. This is particularly challenging because the tags are limited in cryptographic functionality and general performance, but also when there is a need to read multiple tags in a range of practical environments whilst maintaining data privacy. Several...

The popularity of Radio Frequency Identification (RFID) has increased in recent years. Although RFID has many benefits over other identification technologies, there are certain situations that can lead to uncertainty about the true location of the tagged object. In this paper we incorporate the knowledge about the operation of an RFID system and its various failure modes, and evidence from the ...

We propose the use of RFID in sensing applications enabled by passive or semi-passive tags and mobile devices equipped with readers. We experimentally investigate the feasibility of such RFID-based mobile sensor data gathering applications, focusing on UHF RFID devices and indoor scenarios. We examine the impact of various factors, including reader mobility, antenna types and orientation, multi...
